摘要： Method for filter selection of binary configured for determining smallest concentration changes in substance mixtures is provided wherein one or a plurality of low-concentration lead components can be reliably detected in the presence of higher-concentration matrix or background components using the selected broad-band binary filters. The spectral power transmitted or reflected by the substance mixture is detected by a plurality of photosensitive detectors which are spectrally broad-banded and provided with binary filters, the detector signals being used for exact determination of the substance concentrations.

摘要： A diode laser is provided with wavelength stabilization and vertical collimation of the emitted radiation, which allows a small distance of the volume Bragg grating from the emitting surface, a small vertical diameter of the collimated beam and also compensation for manufacturing tolerances affecting the shape of the grating and the lens. The diode laser comprises an external frequency-selective element for wavelength stabilization of the laser radiation, wherein the external frequency-selective element comprises an entry surface facing the exit facet and an exit surface facing away from the exit facet and is designed as a volume Bragg grating; and wherein the external frequency-selective element is designed in such a manner that the divergence of the radiation emitting from the exit facet is reduced during passage through the external frequency-selective element.
